Hi, please assist. Your input will be highly appreciated. I am new to python.my solution is incomplete.how do I add second argument.

Compulsory Task 1
Follow these steps:
● In a file called sum_recursion, create:
o a function that takes a list of integers and an integer as 2
arguments. The integer will represent an index point.
o This function needs to add the sum of all the numbers in the list
up until and including the given index point by making use of
recursion and no loops.
Examples of input and output:
adding_up_to([1, 4, 5, 3, 12, 16], 4)
=> 25

What I have tried:

<pre>def sumoflist(list):
    if len(list) == 1:
        return list[0]
    else:
        return list[0] + sumoflist(list[1:])


list = [5,2,3,1]
sum = sumoflist(list)
print(sum)
